Looking back and going forward: what should the new European Commission do in order to promote evidence-based policy-making?

In this paper, we first give an overview of what has happened in Europe within the area of regulation over the past 5 years or so. We then examine where the new European Commission and the Parliament are with regard to evidence-based and risk-informed policy-making taking a specific look at the importance of transparency among European regulatory agencies, the calls for better regulation that were initiated by First Vice President Timmermans, and the continued mis-use of the precautionary principle. In the final section, we provide a number of recommendations on what the Commission and the Parliament should do going forward including moving away from fish bowl to science-based transparency, making the member states more receptive to science-based policy-making and strengthening the capacity of the European Commission to further promote evidence-based and risk-informed policy-making.     

证券交易策略的风险评估：一个风险收益模型

木文以二项分布为基础,建立一个风险收益模型作为证券交易策略风险评估的理论依据。该模型从理论和实证上证明：在单次交易的收益率不变以及不考虑交易成本的条件下,交易策略的长期风险不依赖于交易次数,只取决于正收益相对负收益的幅度,而不取决于正收益在总交易次数中的比率。该模型作为风险评估工具为证券交易策略提供了理论基础,同时给出了通过计算交易策略的alpha值来估计其长期风险的预测方法。     

Determinants of stakeholders’ attitudes towards a new technology: nanotechnology applications for food,water, energy and medicine

Stakeholder risk and benefit perceptions and attitudes towards a technology matter for the societal response to these technologies. This is especially the case for technological innovations where the public has no direct experience with the technology and its applications. In such cases, expert views are the main source for public opinion formation. Stakeholder risk and benefit perception, and their effect on attitudes towards a new technology (nanotechnology) and its applications were examined in two studies. In a survey, the effect of risk and benefit perception on attitudes to nanotechnology in specific application domains (energy, water, food and medicine) was examined. While risk and benefit perception predicted much of the variance in attitude, experts were more positive about medicine applications and more negative about food applications than could be explained through risk and benefit perception. In the second study, expert focus groups were asked for reasons why food and medicine were seen as more negative and positive than based on the risk and benefit perceptions as measured in the survey. For medicine, the urgency and unique potential of nanotechnology was seen as a reason as why this domain was liked more. For food, the high level of uncertainty about risk assessment and about exposure of consumers and the lack of urgency in applying nanotechnology to food was seen as a reason this domain was liked less. In addition, experts voiced concern about potential negative public response to food applications as reasons for their negative attitude. These results thus suggest that both risk and benefit perception consist of multiple dimensions that require further exploration.     

The role of perceived costs and perceived benefits in the relationship between personality and risk‐related choices

This paper considers how perceptions of costs and benefits can influence the association between personality and risky choice behaviour. We assessed perceptions and behaviours in six domains (ethical; investment; gambling; health and safety; recreational; social) using the DOSPERT and measured personality using the NEO PI‐R. Results from structural equation modelling showed that personality had a direct effect on risky choice behaviour in four domains (social, ethical, gambling and recreational risk‐taking). In addition, perceived costs and benefits mediated the relations between personality and risk‐taking in the five domains (social, ethical, gambling, recreational and investment risk‐taking). Evidence for a mechanism that integrates both direct and indirect effects of personality on behaviour is discussed.     

Five caveats for risk–risk analysis

Risk analysis should be symmetrical in the sense that when evaluating an option for decision-making, we assess the risks that it may increase in the same way as those that it may decrease. However, implementing such symmetry is not always easy. In this contribution, five complications that have to be dealt with are introduced and briefly discussed: (1) We need to take all types of advantages and disadvantages into account, not only the risks. (2) There is more than one way to weigh risks against each other. (3) Decision-makers may legitimately put more weight on the direct effects of their decisions than on more indirect and uncertain effects, in particular, if the latter fall outside of their area of responsibility. (4) When a trade-off between risks is unsatisfactory, we should search for innovative solutions that make the trade-off unnecessary. (5) An exclusive focus on risks does not solve the incommensurability problem.

‘Someone else’s blood’: directed blood donation for neonatal transfusion and parental perceptions of risk

In Canada, parents can give blood exclusively for their child’s transfusion, a process known as directed donation. This qualitative study aimed to understand parents’ perceptions in seeking to provide blood for their newborn. Ten parents whose preterm children were cared for in the Neonatal Intensive Care Unit of one Canadian hospital were interviewed. The beliefs and experiences of parents with regard to directed donation were analyzed with reference to their understanding of the risks and benefits of this form of transfusion. Interview data revealed that parents had little knowledge or understanding of the medical benefits and risks of directed donation and based their decision to seek this type of transfusion largely on emotional grounds. In addition, despite their preference for directed donation, most infants whose parents were interviewed in this study, for practical reasons could not be given this type of transfusion. This may have magnified risk perceptions of non‐directed transfusions. Parents need to be better informed about the medical risks and benefits of directed donation and the actual likelihood that their child will be able to receive this type of transfusion.     

Risk assessment for public–private partnership projects: using a fuzzy analytic hierarchical process method and expert opinion in China

Public–private partnerships (PPP) have been widely used in China to procure public facilities and services. Complicated problems in PPP projects in China arise because of a variety of risk factors. A proper risk assessment model is needed to identify risks and provide risk response strategies for future Chinese PPP projects. The fuzzy analytic hierarchy process (F-AHP) method provides the ability to solve complex risk assessment of PPP projects. Current risk assessment models are limited to PPP projects in specific countries and do not consider unique risks in China, especially political, economic, social, and legal risks. This paper designed a risk evaluation index system for PPP projects based on the Delphi expert investigation method, and then established an optimized risk evaluation model for PPP projects in China using the F-AHP method. The risks identified are confirmed by interviewing experts from Chinese local government departments, private enterprise, third-party intermediary consulting and regulatory agencies, and academic organizations. The results show that the risks that ranked among the top ten are closely related to China’s political and economic policies and relationships among stakeholders. It can be concluded that government authorities play a critical role in providing a favorable political, social, and economic environment and an effective institutional framework for PPP projects. Furthermore, it is also important to deal with relationships among stakeholders based on the public–private ‘win–win’ principle. This study provides risk response strategies, addressing key issues from eight aspects: an impeccable legal and regulatory framework; a central coordinating and regulating PPP authority; supportive governmental authorities; institutional capacity-building; favorable economic conditions and viability; community, partner, and moral accountability; clear division of responsibilities through contracts; and effective advisory management. These effective measures may be useful in reducing the adverse effects of risk for PPP projects in China.     

Exclusions and the Demand for Property Insurance

The paper examines property insurance contracts in which consumers choose the upper limit on coverage. Exclusions are of two types, and both reduce the demand for insurance of the included perils. A practical implication is that an insurer can raise the demand for fire insurance by offering an earthquake rider, and profit from the rider even when the premia are ceded in such a way that the rider does not raise profit directly. The results do not require assumptions about correlations between included and excluded losses, which is interesting because correlations are decisive in most of the other literature on background risk.     

Public’s perceived overcrowding risk and their adoption of precautionary actions: a study of holiday travel in China

The importance of travel risk has been recognized, but only a limited number of studies have been conducted on this risk and the precautionary actions the public may take to manage it during holidays. This study applied the protective action decision model and the protection motivation theory to examine the public’s intent to take precautionary actions during holiday times to handle the risk of overcrowding in China. Our survey showed that efficacy-related attributes of precautionary actions were positively correlated, whereas resource-related attributes were negatively correlated, with the intention to take precautionary measures. Risk perception also significantly influenced the adoption intention, but the amount of variance in the intention to adopt precautionary actions that was motivated by risk perception was lower than that related to efficacy-related attributes. In addition, we found that risk perception mediated the influence of past overcrowding experiences on people’s intention to adopt precautionary measures. Travel frequency, length of time spent away for the holiday, and the number of underage family members involved were significantly correlated with the intention to adopt precautionary actions. Finally, this paper discussed suggestions and implications for travelers, tourist departments, and related stakeholders.
